Patent JP-2000021559-A (JP)
Title: Microwave oven
Inventor: TAKEI TAMOTSU
IPC: H05B6/68
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To restrain the overshoot of input current at the time of starting heating operation and utilize rated power to the utmost to reduce the heating time. SOLUTION: An initial current setting value II lower than an input current setting value IR that is the setting value of a current flowing through a high- voltage power conversion part is set so that the input current of the high-voltage power conversion part should be controlled to be set to the initial current setting value II at the time of starting heating operation(time t0), and thereafter, it is controlled to be set to the input current setting value IR by means of switching, and thus, the overshoot of the input current is restrained.  When the temperature of a magnetron is high, the control is switched over from the initial current setting value II to the input current setting value IR after a time T2 (for instance three seconds) from the heating operation starting time (the time t0) has passed, and when it is low (for instance, 70 deg.C or lower), the control is switched over from the initial current setting value II to the input current setting value IR after a time T1 (for instance five seconds) has passed, so that the heating time is reduced depending on the temperature of the magnetron.

Title: Angle detector
Inventor: ITOU SUSUMU
IPC: G01B7/00
Filed: 1981-11-18
Abstract: PURPOSE:To obtain an inexpensive angle detector which is easily assembled and adjusted by using a sine and a cosine wave to drive a couple of magneto-resistance effect elements which are placed on the rotating shaft of a rotating magnet and have a 45 deg. difference between directions of sense currents, and then obtaining the output difference between both. CONSTITUTION:A revolving magnetic field which changes only in direction while holding cnstant intensity is generated through the rotation of a permanent magnet 30. On the other hand, outputs of a sine-wave voltage generating circuit 43 and a cosine-wave voltage generating circuit 44 are applied to MR sensors arranged on the rotating shaft. The MR sensors are so arranged that at least their sense current directions are at 45 deg.. When the difference in output between those sensors is detected by a differential detecting circuit, its output signal is out of phase with the sine-wave voltage by time DELTAt proportional to the angle theta of the permanent magnet. A phase difference detecting means 46 detects said phase difference, which is converted by a turning-angle detecting means 47 into a turning angle to be outputted.

Title: Reciprocating compressor
Inventor: YOKOMACHI HISAYA
IPC: F04B27/08
Filed: 1994-08-05
Abstract: PURPOSE:To reduce the occurrence of overcompression and to suppress the generation of noise due to vibration of a generator by reducing an amount of gas over-compressed in a bore. CONSTITUTION:Bores 11a-11e and delivery chamber are intercommunicated through intercommunication passages 30a-30e extending through a valve plate and allowing a microamount of gas flow to extent to prevent an influence from being exercised on compression efficiency. Thereby, refrigerant gas flows from the high pressure side to the lower pressure side according to a pressure difference between the bores 11a-11e and the delivery chamber, which are intercommunicated through communication passages 30a-30e. Since, when a delivery valve part 24a is opened and transferred to a delivery process, a pressure in the bore 11a is higher than a pressure in the delivery chamber, a microamount of high pressure gas flows from the bore 11a to the delivery chamber through the pressure regulation passage 30a. A gas amount over-compressed in the bore 11a after the delivery valve part 24a is opened is reduced by an amount equivalent to an amount of gas flowing out to the delivery chamber from the bore 11a through the pressure regulation passage 30a.

The circuit 11 delivers periodically a compound code so in responding with telephone sets 61-6n respectively. A decoder 8 delivers the code so after ecoding and separating it into the type-based information ro and phase information po. A rigning tone transmission control circuit 3 controls ringing tone intermitting contacts 41-4n on a basis of both information ro and po and produces the ringing tone at each telephone set.

Title: Measuring method for external pressure of fuel rod
Inventor: HASEGAWA ISAO
IPC: G01M3/24
Filed: 1980-12-29
Abstract: PURPOSE:To measure the internal pressure of a fuel rod in a nondestructive way, by measuring the speed with which a ultrasonic wave propagates a coated tube of the fuel rod. CONSTITUTION:The pulse is produced from an oscillator, and the pulse is radiated to a coated tube 3 of a fuel rod 12 by an oscillator 2. The radiated pulse propagates through the thick part of the tube 3 toward an arrow mark to receive a receiving element 5 and is transmitted to the oscillator 1 by a receiver 5 to repeat the oscillation of pulse. The lower the pulse frequency the higher the internal pressure of the rod 12. Thus the internal pressure of the rod 12 is measured in a nondestructive way.

Title: Measuring method and equipment therefor
Inventor: KONDO MASAHIKO
IPC: H01L21/66
Filed: 1985-08-26
Abstract: PURPOSE:To accomplish wafer probing in a short period of time and with high efficiency by a method wherein the effective pellet region on a wafer is divided into units respectively containing a plurality of chips and the chips belonging to a unit are subjected to probing simultaneously. CONSTITUTION:An effective pellet region 3 on a wafer 2 is divided into units 6 respectively containing an optimum number of chips for the accomplishment of effective probing. Data on said dividing is stored in a control section 13. A sensor 12 detects the geometry of the wafer 2 and the control section 13 drives a motor 9 or 10 for the determination of the center of the wafer 2. The locations of the chips relative to the determined center are stored in the control section 13. An X-Y table 8 is driven by the motor 9 and 10 for the probe of a probe card 7 to easily probe into a first unit 6a and, subsequently a stage 1 is caused to move on for the probing by the probe card 7 into other units 6 that follow the first unit 6a. This method prevents unnecessary probing into the regions surrounding the wafer 2 where there are no chips, which contributes to the enhancement of wafer probing efficiency.

IPC: H01L27/108
Filed: 1992-06-19
Abstract: PURPOSE:To improve data storage performance of a memory cell by reducing a junction leak between a semiconductor substrate and a diffusion region of a transistor. CONSTITUTION:A bird's beak portion of an SiO2 film 14 as a field oxide film is removed which portion covers one diffusion layer 17 of a transistor 16 that is connected to a capacitor 18 that constitutes a memory cell. With this structure, there is no stress concentration in a boundary between a bird's beak portion and a silicon substrate 11 and, therefore, the density of boundary states in a portion enclosing the diffusion layer 17 is low. As a result, the density of generation and recombination centers in this portion is low and, therefore, a junction leak between the diffusion layer 17 and the silicon substrate 11 through the generation and recombination centers is small.
